Background

The name "acacia" is derived from the Greek word "akis" meaning "sharp point," and relates to the sharp thorny shrubs and trees of tropical Africa and Western Asia that were the only known acacias at the time that the name was published. The Australian acacias are commonly called "wattles" because of their pliable branches that were woven into the structure of early wattle houses and fences.

Acacia is commonly present in chewing sticks, mainly as an antimicrobial with activity against Streptococcus fecalis. Acacia has also shown some cholesterol-lowering and antidiabetic properties, although there is insufficient evidence in support of these uses.

Acacia is generally considered to be safe. Adverse reactions appear to be mild, with occasional gastrointestinal symptoms.
